1.Aggregate demand curve of an economy is given by AD = 51 - 0.2P, the long-run aggregate supply, LRAS, is 30 and the short-run aggregate supply is given by SRAS = 0.3 P (all output measures are in US$ billions and the price level is given as an index number). What is the output gap as a percentage?

2.Aggregate demand curve of an economy is given by AD = 51 - 0.2P, the long-run aggregate supply, LRAS, is 30 and the short-run aggregate supply is given by SRAS = 0.3 P (all output measures are in US$ billions and the price level is given as an index number). What could be the unemployment rate if the natural rate of unemployment is 4%?

3. Aggregate demand curve of an economy is given by AD = 51 - 0.2P, the long-run aggregate supply, LRAS, is 30 and the short-run aggregate supply is given by SRAS = 0.3 P (all output measures are in US$ billions and the price level is given as an index number). Assume that the present status of the economy is the result of a demand shock. What should be the original price level when the economy was in equilibrium?

4.Aggregate demand curve of an economy is given by AD = 51 - 0.2P, the long-run aggregate supply, LRAS, is 30 and the short-run aggregate supply is given by SRAS = 0.3 P (all output measures are in US$ billions and the price level is given as an index number). Assume that the present status of the economy is the result of a demand shock. What should be the price level when the labor market adjusts and the economy will be in an equilibrium?

Solutions

Expert Solution

1.

Aggregate Demand:

Short-run aggregate supply:

At the short-run equilibrium:

Therefore,

Then the output gap is

===============================================

2.

By Okun's law every percentage point deviation of the unemployment rate from the natural rate, there will be a 2 percentage point output gap. That is by Okun's Law

=================================================

3.

If this is due to demand shock then at previous long-run equilibrium,

==================================================

4.

If the gap is due to demand shock at new long-run equilibrium

Consider the aggregate supply-aggregate demand (AS-AD) model. The long run AS curve (LAS) is considered to be vertical at the full employment level of income.

Are there any risks associated with an increase in the long run AS in your examples (please, briefly discuss the risks involved)?
